You need 19s to clear 15" brakes. Unless you

Hot rodding 102 --- "ya gotta cut to cure".


I'm thinking that Ron Sutton has done plenty of math on the brakes that are now installed and they're no doubt "more than adequate" --- particularly over the 12" two piston fronts and the single C4 caliper rears.....

Dave -- the 18" wheels are about reducing sidewall roll because I want to be able to lap Gaetano next time out - which means carrying a lot of speed into and thru the corners... and I was rolling those 45's over onto the sidewalls....


HAHAHAHAHAHAHAHAHAHAHAHA

My math says your adding rotating mass and will over brake those 245's but hey, what do I know.

Looking forward to spanking you like a red headed step child.

With 4 tires that are twice as wide --- and more horsepower --- and 80 more cubic inches.... you SHOULD be able to.... Should being the critical word there. LOL

All in good fun buddy. More cubic inches and you still pull me

I've got work to do for sure.

We all do.... it's never ending with these kinds of cars. We're either improving (right...) or fixing... or waiting to do either of those things. UGH!

All fun though and I have to say I love it.

I have been running 245'-18's on the front of my
Pantera for over 8 years now. Brakes are 12.2 wilwood 6 piston
Bush grand national stuff... Yes roundly round stuff
Never have locked or flat spotted any tires. I do have
315-18's out back. Car is mid engine and it took a while
To balance out but that is what it is about ..proportioning valve

He'll my old mustang (Chet's car now) had Baer 6 pistons
Up front and drums in the back. Car is very light but still
Stopped very well. 245-16's all the way around
That car was 2810lbs so that helps
Greg's should be lighter. Weight always wins in my book

Pantera is beefy at 3040 lbs

There's more to it than just how many pistons etc.... we're going to a different compound pad which will be "nicer" to the rotors.... we wanted to be able to run the Spec 37 Rotor... and my old brake system wouldn't allow that combo.

Pads are cheap - rotors get spendy. I was having to replace them too often, without the corresponding brake performance. The Lotus has done as many if not more laps - at faster lap times - and I haven't touched the brakes other than to inspect them. That system is "correct" in my book. It's a TINY - make that MINUSCULE - brake system.

We also wanted to upgrade the bearings - and that alone made choices of other parts - and then toss in the "as long as we're doing it right - let's do it right!".


The Mustang is 3015#'s.... Not sure how you got Chet's down to 2800 something. But I know he's fast. One Sunday we chased a Turbo Porsche around for several laps at Sonoma. Chet was able to keep right on his tail. I was surprised - as I'm certain - so was the Porsche owner.

I understand that brake pads can make a huge difference
I was running almost street pads on the Pantera for many years
and last year moved to a more race type pad.. car stops even
better by a long shot...

65 GT350r cars... back in the day were 2650 lbs-race weight
I was going to pull the Windows in Chets car and they
say that was another 90lbs.. I see he took the rear bumper
and pulled it.. I put one on when I bought it... In thinking
the Dart block is a little heavier than the sportsman I destroyed

That car with a 455hp motor (now it is 530hp) would run
with the Porshes all day long.. it was very easy to drive
and a lot of fun...good to see him out there beating on it
